Answer:

[tex]f'(x)=-a^2e^{-ax}[/tex]

General Formulas and Concepts:

Calculus

  • Chain Rule: [tex]\frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)[/tex]
  • Derivative: [tex]\frac{d}{dx} [e^u]=e^u \cdot u'[/tex]

Step-by-step explanation:

Step 1: Define

[tex]f(x)=ae^{-ax}[/tex]

Step 2: Find Derivative

  1. Derivative eˣ [Chain Rule]:                    [tex]f'(x)=ae^{-ax} \cdot -a[/tex]
  2. Condense/Simplify:                               [tex]f'(x)=-a^2e^{-ax}[/tex]
